Pasture growth is a grazing resource and our main soil development tool. In the tree crops at this time of year we mow to set back the grass, and free up the soil and water resources for tree growth and fruiting.

Winter grazing only removes about 50% of the leaf area, with very little root growth retardation. The pasture recovers very quickly. The spring mowing removes almost 100% of the pasture leaf area, and substantially sets back the grass. Grass roots die, soil microbes decompose these, and tree roots and their fungal associates then explore those former grass root pathways for nutrients.

Early Spring this year saw cool weather, rain, a full soil profile of stored water, and surplus water in the upper profile.So we let the grass in the tree rows keep growing, using that surplus moisture, and adding more root material to the orchard soil.

Timing of the main Spring mowing depends mostly on water availability …. is the soil moisture better used for more grass growth, or saved for the trees?
Other factors we consider are
– availability of pasture for the goats, and of mown pasture for chicken forage
– very dense and vigorous grass growth competing with the trees…. size of trees vs the grass
– reducing fire risk for the coming summer, trying to allow time for surface mulch to begin to decompose
– use the tractor and fuel as little as possible while still maintaining good production and fire safety
– attraction and hosting of pollinators in the orchard other than honeybees, and insect predators for pest control services
– forage for honeybees, mainly the pollen resource for hive increase in Spring from capeweed daisy Arctotheca calendula

This very dense grass growth among smaller trees in the olive grove was probably beginning to compete with the trees.

Our very happy news is that Cecilia Lundmark has come to live at Murrnong.

Cecilia is an all round wonderful person who brings many skills and much awesomeness to Murrnong.

Cecilia and David were married in July, in her native Sweden.

7th October 2016, goats grazing and David standing in a row of pasture between 16 year old olive trees. This was close grazed and almost bare in early May, after having been grazed 4 or 5 times through the summer. In the last 6 months of cool wet conditions, it has been grazed two more times. Other than some woodchip compost under the trees, the pasture itself has not had fertiliser added of any kind for about 16 years. No ploughing either. Just pulse grazing and pulse mowing. Annual and perennial plants go well together, combined with high impact short rotation grazing.
Capeweed growth on orchard farm track, very little capeweed elsewhere.
Capeweed, Arctotheca calendula, can be seen flowering on the edge of the footpath in the foreground of the second photo, and on the farm track above. Capeweed is a fast growing annual that has grown well around tracks and high traffic areas, and in other places where the soil is bared. The capeweed flowers are providing pollen for the spring bee build-up, and the capeweed roots are opening and repairing the soil. If we stopped using the tracks they would heal and regenerate and revert to pasture. With continued good pasture management there is no risk of this plant invading from the tracks and taking over the pasture areas.

Kate Holmes came over to lead a sauerkraut making session. Here, after bruising the sliced cabbage on the table by working a heavy rolling pin over it, she is punching the cabbage into the pot with layers of salt. With Anna Turner.

It is a rare opportunity to lay out a new treed parkland within a township area. What criteria to use to choose the trees and shrubs? Who will be motivated to maintain this privately owned parkland? How will the trees and grass be managed?

This 8 hectare site within Avenel village will have a 10 lot residential subdivision, Belmont Hamlet, with the greater portion of the space to become parkland. For me, David Arnold, it was a pleasure to work with Jim and Winifred Peart, the developers, on this parkland project. I have been working with Jim on occasional tree development projects since 1998.

Jim and Struan will care for these private land parkland plantings while they are young, including weeding around the trees and mechanical mowing, but such altruistic expense cannot be expected to last forever. In the longer term we had to consider how to allow the future park manager(s) to obtain a yield from this land, and how to ensure that these future managers value and appreciate the trees.

So we anticipate future grass management by grazing animals, probably sheep and/or goats. The common parkland form, of an open wooded grassland, can be ideal for grazing. We selected attractive shady long lived species, all giving a passive yield of shade for animals and people, and most of which also give a direct grazing and possible human food yield. So… a number of hardy oak (Quercus) species for acorns, Carobs, also for autumn fodder supplement, Kurrajong (Brachychiton populneus) which can give foliage fodder, plus some Boree (Acacia pendula), and a few Peppercorn trees (Schinus molle). A mix of regional natives and introduced species.
